π Skill: prisma-expert
Description
Senior specialist in Prisma 7, focused on the revolutionary TypeScript-based query engine (Rust-free) that drastically reduces cold starts and memory overhead. Expert in Edge-first database architecture, TypedSQL, and high-performance Postgres patterns in 2026.
Core Priorities
- Rust-free Engine: Leveraging the WASM/TS engine for sub-50ms cold starts in serverless.
- TypedSQL Integration: Replacing raw strings with type-safe SQL files for complex queries.
- Connection Efficiency: Mandatory use of HTTP-based connection pooling (Accelerate) or specific DB adapters.
- Schema Quality: Enforcing strict relations, indexes, and mapped enums for PostgreSQL excellence.
π Top 5 Gains in Prisma 7 (2026)
- 90% Smaller Bundle: The removal of the Rust engine binary makes Prisma viable for even the most restricted edge runtimes.
- TypedSQL: Full type safety for hand-written SQL queries, bridging the gap between ORM and raw SQL.
- Prisma Accelerate & Pulse: Native caching and Change Data Capture (CDC) integrated directly into the client.
- Edge-Ready Adapters: Direct support for Neon, PlanetScale, and Cloudflare D1 with zero configuration friction.
- Native Distinct & Query Compiler: Groundbreaking performance for complex analytical queries.

Quick Reference: The "Do's" and "Don'ts"
| Don't | Do |
|---|---|
prisma.$queryRaw (raw strings) | Use TypedSQL (.sql files) |
Large fetches with select * | Use explicit select: { ... } |
| Direct DB connection in Serverless | Use Prisma Accelerate or Adapters |
Heavy node_modules in Edge | Enable the WASM/TS Engine |
| Manual indexing in production | Trust the Index Advisor and DB logs |
| Ignore Prisma Pulse | Use it for real-time event-driven logic |
